Give me some methods you might use to protect yourself. As many ways as you can possibly think of.

It's illogical to make an attempt to answer such a question since if there is no known observations and theory of it then we don't know how it works. If we don't know how it works then we can't tell you anything about how to make it stop working.

I'm curious. What made you think of asking such a question and didn't it occur to you that if it doesn't exist then we don't know how it works and as such if it did exist then we couldn't know how to make it not work? Thanks! :)

As I don't use youtube, would you mind defining what you mean by silent sound? And how it is dangerous? The 'Silent sound' I think of is when waves quench. And EM radiation isn't thoughts, never has been, never will be. You have electrochemical body constituents if that is what you mean?

The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks (or, with speech modulation, spoken words) induced by pulsed/modulated microwave frequencies. The clicks are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. These induced sounds are not audible to other people nearby. The microwave auditory effect was later discovered to be inducible with shorter-wavelength portions of the electromagnetic spectrum. During the Cold War era, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish[1] information on the nature of the microwave auditory effect.

Pulsed microwave radiation can be heard by some workers; the irradiated personnel perceive auditory sensations of clicking or buzzing. The cause is thought to be thermoelastic expansion of portions of auditory apparatus.[2] The auditory system response occurs at least from 200 MHz to at least 3 GHz. In the tests, repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds. The perceived loudness was found to be linked to the peak power density instead of average power density. At 1.245 GHz, the peak power density for perception was below 80 mW/cm2.[citation needed] However, competing theories explain the results of interferometric holography tests differently. [3]

... At 1.245 GHz, the peak power density for perception was below 80 mW/cm2.[citation needed]

That's 800 Watts per square meter : around two orders of magnitude below sticking your head in a microwave oven, where you'd hear your head cooking like a TV-dinner.

If microwaves were the source of the voices in the head there would have to be an unobstructed line-of-site between the voice-hearer and very powerful microwave source , e.g. a one kiloWatt source in the same room.

A disadvantage is that microwaves are limited to line of sight propagation; they cannot pass around hills or mountains as lower frequency radio waves can

If they can still hear the voice at constant volume in all the rooms of their home then auditory hallucination is by the far the most probable explanation, not mind-control rays from the government.

From what I read about the Frey Effect the subject doesn't hear actual sound just language the brain interprets as coming from a sound source without actually hearing it aloud. But all this is sort of off the subject of what I was asking. Would you opt for a conductive material, or grounded metal? A grounded metal hat would seem sort of impractical no? Lets imagine hypothetically 100 years from now we were in an all out war, and all the countries of the world had practical field weapons that utilized EMF waves, sound waves directed at a person's head. How would you go about designing protective headwear as easily as possible?
